Therapeutic alliance (TA) is the agreement between caregiver and patient during the care process. Therapeutic adherence is a major issue for the management of Juvenile Idiopathic Arthritis (JIA) requiring child’s strong ability to follow treatments. The aim of this study was to evaluate the relationship between TA and adherence in patients with JIA.
Observational, cross-sectional, multicenter study. Children, with JIA, aged 8-16, were included. Children, parents and physicians completed the Helping Alliance Questionnaire (HAQ-CP) for assessing TA. Adherence was measured using the Child/Parent Adherence Report Questionnaire (CARQ & PARQ). Demographic data, disease characteristics, current treatments and social environment were collected. The univariate relationship between TA and adherence, was studied by Pearson correlation coefficient. The multivariate analysis used a multiple linear regression model.
119 patients were included: 68.9% girls, mean age (SD) 12.4 (2.9) years, disease duration 73.1 (48.2) months. JIA was in remission (52%), in low activity (32%) and active (16%). TA scores were high (>80/100) for children, parents and physicians. HAQCP was highly correlated with CARQ (r=0.31; p <0.001) PARQ (r= 0.37; p <0.001). In univariate analysis, disease activity (p < 0.05), place of residence (p<0.01) and family status (p<0.01) were associated with child's TA. In multivariate analysis, only the place of residence (p<0.001) and the family status (p<0.05) remained associated with TA.
TA strongly influences therapeutic adherence and therefore may be important for treatment effectiveness.
